RuntimeError

Seems there is bugs in the code

""" Traceback (most recent call last): File "exp_runner.py", line 392, in runner.train() File "exp_runner.py", line 105, in train data = self.dataset.gen_random_rays_at(image_perm[self.iter_step % len(image_perm)], self.batch_size) File "/home/kailu/NeuS/models/dataset.py", line 118, in gen_random_rays_at color = self.images[img_idx][(pixels_y, pixels_x)] # batch_size, 3 RuntimeError: indices should be either on cpu or on the same device as the indexed tensor (cpu) """

img_idx is a gpu tensor while self.images is a cpu tensor

I had the same issue. Solved by using torch 1.80 as specified in the requirement file.

Worked for me as well, thanks!

For users like me who have to use higher versions of PyTorch due to GPU limitations, removing some ".cpu()" in the code and checking the device of the tensors related to the error message can solve the problem.

Yes, I have only modified the device of some tensors involved in thegen_random_rays_at function in models/dataset.py to make it work.

can you provide more details about how to modify the codes?

adding .cuda() or to(device) to images and masks in line 118 and 119 worked for me

In torch there is a command <.get_device()> to help detect the used device. With this method, I checked the function in dataset.py line-by-line, I managed to run the code by following changes: make sure that the color and mask in the final return line is also cpu'd, and also the self.images and self.makss needs to be sent to cuda via <to.(self.device)> , just like the img_idx, pixels_y, and pixels_x.

in my case modifing in this way it works

    self.images = self.images.to(self.device)

It works! a big thanks to you!
